Hint: Use the table below to help determine the cause of the problem symptom. The potential causes of the symptoms are listed in order of probability in the "suspected area" column of the table. Check each symptom by checking the suspected areas in the order they are listed. Re ...

Vehicle speed sensor "A"
description The speed sensor detects the wheel speed and sends the appropriate signals to the skid control ecu. The skid control ecu converts these wheel speed signals into a 4-pulse signal and outputs it to the ecm via the combination meter. The ecm determines the vehicle speed based o ...

Shift solenoid "d" performance (shift solenoid valve s4)
System description The ecm uses signals from the output shaft speed sensor and input speed sensor to detect the actual gear position (1st, 2nd, 3rd or o/d gear). Then the ecm compares the actual gear with the shift schedule in the ecm memory to detect mechanical problems of the shift s ...
